A method for detecting anomalies in digital images of products, wherein a region of a digital image is detected as a maximum anomaly if the value of a property of the region is greater than a predetermined maximum threshold, and/or wherein a region is detected as a minimum anomaly if the value of the property of the region is less than a predetermined minimum threshold. The maximum threshold value and/or the minimum threshold value are determined in a learning process using relatively few digital images based on a statistical distribution of the largest or smallest values of a specific quantity used for the detection of anomalies in digital images to be examined.

Method and apparatus for the detection of anomalies in two-dimensional digital images of products

A test device for the irradiation of products which are fed into a housing along at least two tracks. At least one separate sensor is provided for each track in order to separately monitor the arrival at a target position selected individually for each track preferably within the housing of the test device.

Test device for irradiating products on a conveyor route

An X-ray detector device for a device for the X-ray inspection of products includes a first line detector with a first discrete spatial resolution, a second line detector with the same or lesser second discrete spatial resolution, and an evaluation and control unit. The first line detector is operable to capture X-radiation in a non-spectrally resolved fashion along a first capture line transverse to a product movement direction to generate first image data. The second line detector is operable to capture the X-radiation in a spectrally resolved fashion along a second capture line parallel to the first capture line to generate second image data. The evaluation and control unit is operable to evaluate the first and second image data to detect at least one predefined feature of the product with the first discrete spatial resolution by combining the items of information contained in the first and second image data.

X-ray detector device and device for the X-ray inspection of products, in particular foodstuffs

The invention relates to a method for ascertaining a net weight of a product in a product range, plurality of contiguous product ranges form a product chain and a total weight of the product chain is ascertained. The product chain is X-rayed to ascertain values that correspond to the radiation that penetrates a defined range of the product chain. The ascertained values are used to ascertain a total value for the entire product chain. A product range with a single product is selected by means of evaluation of the ascertained values. A value of the product range is formed from the ascertained values. A gross weight of the product range is ascertained therefrom. The net weight used for the single product is approximately the weight or the net weight is ascertained from the difference between the weight and a prescribed or ascertained weight of the product range without a product.
